SPECIFICATION forming part of Letters Patent No. 692,721, dated February 4, 1902. Application filed May 11. 1900. Renewed December 24a 1901. vSerial No. 87,048. (No model.) i

T all whom may concer-ie:

Be it known that I, CYRUs JAY SELTZER, of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in af Combined Atomizer and Nebulizer, of which the following is a specification.

My invention relates to a combined atomizer and nebulizer-that is to say, to an apro paratus from Which liquid may be ejected either in the form of a jet or spray or in a nebulous or cloudy condition; and it consists in the mechanism as hereinafter described and claimed.

part of this specilication, Figure 1 is a central vertical sectional View of my combined at-y omizer and nebulizer. Fig. 2 lis a horizontal section on the line a: of Fig. 1. Y Fig. 3 shows 2o an attachment to my combined atomizer and nebulizer by means of which oxygen or other gas or a vapor maybe commingled with either the atomized or the nebulized Iluid.

Like figures of reference indicate like parts in each View.

l is an outer receptacle for the liquid 2 to be atomized.

3 is an inner receptacle for the liquid 4 to be nebulized.

5 is any usual form of nebulizing-tube.

6 and 7 are respectively the well-known form of inner and outer atomizer-tubes and are provided with a'detachable tip 8.

The cap 9 is providedwith a portion 10, having an aperture in which is secured the block 11. The block 11 is provided with three substantially longitudinally arranged:

passages 12, 13, and 14 and also with a recess or passage l5, intersecting the passage 13 at 4o its top. The block is also provided with a short passage 16, connecting passages 14 and` 15 and arranged with 'its axis in the plane containing the axes of passages 13 and 14. A three-Way cock 17v is rotatably mounted in the passage 15 and is provided with'a passage I18 and an orifice 19, opening from the periphery of the cock to the passage 18. The orice 19 is so arranged or positioned that by rotating the cock 17 communication can be 5o established either between the passages 18 and 13 orbetween passages 18 and 14. The

In the accompanying drawings, forming usual inner atomizer-tube 6 passes through the passage 14, sufficient space being left between the exterior of the tube and the Walls of the passage to provide au air-passage.

The operation of my above-described modified form of combined atomizer and nebulizer i's as follows: When operating as a nebulizer, the tip 8 is removed. The cock 17 is turned in the position shown in Fig. 1 of the-drawings, with the inner end of passage 18 communicating through orifice 19 With passage 13, vthe outer end of passage being arranged in communication With the ordinary form of atomizer-bulborothersuitable air-supply. Air is then forced in through passage 18, orifice 19, and passage 13 to thenebulizer-tube 5 and nebulizes portions of the liquid in receptacle 3. The nebulized liquid then issues from said receptacle through passage 12 and tubeY 7. When it is desired to use the apparatus as an atomizer, the tip 8 is secured in place. The cock 17 is turned through an angle of ninety degrees from the position shown in Fig. l,

thus bringing the orifice 19 into position to establish communication between passages 18 and 14.k through passage 18 and orifice 19into the passage 14. Here a portion of the air flows up- `Wardlythrough the outer tube 7 and escapes through the tip by means of the passages provided by the flattened sides ofthe end oftube 6. The other-portion of the air passes downwardly through passage 14 into the receptacle 1, Where it exerts a sufficient pressure on the liquid contained therein to force a portion of it up through tube 6 into the tip 8. The air passing through the tip sprays the liquid in the Well-known manner. lf desired, the element can be rigidly secured in the position illustrated in Fig. l, in which case it could be employed only for supplying air to the nebulizertube 5. This would necessitate 'the usek of an additional nipple 21 (shown in broken lines in Fig. 2) for establishing connection between the air-supply and the chan-l (See Fig. 2.) Air is then forced IOO corresponding parts in the two figures being designated by similar numerals. At the right in Fig. 3 I show an attachment by means of which a gas or vapor maybe commingled with the atomized or nebulized liquid issuing, respectively, from receptacles 1 or 3. If it be desired to employ a gas, such as oxygen, in this manner, suitable reagents for producing it are placed in the Vessel 22, and the gas so produced is led to the interior of cap 9 by means of the connecting-tube 23, provided with a regulating-cock 24. 25 is a nipple by means of which air can be forced through tube 65 into vessel 47 whenever necessary or desirable in the production of a gas.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a combined atomizer and nebulizer, an outer receptacle for containing liquid to be atomized, a cap secured to the receptacle and provided with an apertured portion 10, an outer atomizer-tube secured to said cap and in communication with said aperture in the portion 10, a block closely fitting in said aperture, an inner receptacle for containing liquid to be nebulized carried by the block, said block being provided with a passage connecting the inner receptacle and the aperture and with a second passage connecting the outer receptacle and the aperture, an inner atomizer-tube in the outer receptacle and passing through said second passage into the outer atomizer-tube, said block being provided with a third passage extending from the interior of the block into communication with the inner receptacleand with a passage connecting said second and third passages, a three-Way cock arranged to connect a Huidpressure supply with either said second or said third passage, and a detachable tip carried at the outer ends of the inner and outer atomizer-tubes.

2. In a combined atomizer and nebuiizer, a cap 9 having an apertured portion 10, a block 11 extending through said aperture and secured therein by an air-tight connection, a receptacle 1 for containing the liquid to be atomized secured to the bottom ot' said cap, a receptacle 3 for the liquid to be nebulized located within receptacle 1 and secured to the bottom of the block 11, said block provided with passages 12 and 13 arranged with their lower ends in communication with the intorior of receptacle 3, a nebulizer-tube 5 Within receptacle 3 and arranged with its air-passage in communication With passage 13, said block being provided with passages 14 and l5 and an aperture 16, the passage 14 arranged With its lower end in communication with receptacle 1, the passage 15 arranged in communication with passage 13, the aperture 1G connecting passages 13 and 11, a three-Way cock 17 rotatably mounted in said passage 15 and provided with passages 18 and 19, a dischargetube 7 carried by the cap 9 and communicating therewith above the portion 10, a liquidtube G of smaller external diameter than the passage 14 and arranged to pass through said passage, said tube G arranged with its lower end suitably located Within receptacle 1, and its upper end extending Within outlet-tube 7, and a spray-tip suitably connected to the upper ends of tubes 6 and 7, substantially as described.

In testimony vvhercot` I hereunto set my hand, this 5th day of May, 1900, in the presence ot' two attesting Witnesses.

CYRUS JAY SELTZER.
